Aiming help !

Hi there ! 

Long time no see, sorry about that, but I'm trying to manage so I can work more on the projet soon... Hopefully you will like what's coming ! :) For now, here is an update to help new comers and other who find difficult to send the ball on the other court.

- Aiming help : when the ball is getting out of opponent court, but not too much, enjoy a little help :) 

- Mitigate touch on the ball

- Fireball doesn't appear anymore if angle is too high

- Remove unecessary permissions and preparing for Applab

Enjoy !
